Serpentine coils for compact cooling systems



Compact heat exchangers, especially those of serpentine design, are widely used for cooling in many industries, products and systems, from consumer products to IT cooling to military applications. In recent times, with the advances in microfluidics and progress in manufacturing, compact microchannel heat exchangers are becoming widespread. The principal idea behind using microchannel heat exchangers is their potential for enhanced heat transfer capabilities. The use of such heat exchangers enables the transfer of large amounts of heat while benefiting from high heat transfer coefficients.
